Randomized Controlled Trial Clinical Trial
Endotracheal suctioning in adults with head injury.
The purpose of this study was to determine the method of endotracheal suctioning (ETS) that resulted in the least compromise to the cerebrovascular status of adult patients with severe head injuries. A two-group (two vs three ETS), two-protocol (100% tidal volume [VT] vs 135% VT) design was used. The dependent variables were mean intracranial pressure (MICP), mean arterial pressure (MAP), cerebral perfusion pressure (CPP), heart rate (HR), and oxygen saturation (SaO2). ⋯ No significant difference was found for SaO2 for either of the protocols regardless of number of suction passes. No significant differences were found between two- and three-ETS groups for any of the dependent variables. All groups, however, regardless of number of suction passes, demonstrated a cumulative increase in MICP, MAP, and CPP with each consecutive suction sequence.(ABSTRACT TRUNCATED AT 250 WORDS)

The Bullard laryngoscope is a rigid fiber-optic device that offers a new approach to oral laryngoscopy. In this report, I present five cases illustrative of the use of the Bullard laryngoscope in patients with demonstrated or suspected difficult laryngoscopy and intubation.

Randomized Controlled Trial Comparative Study Clinical TrialInfant responses to saline instillations and endotracheal suctioning.
The study examined the effects of endotracheal suction with and without saline instillation on neonates with respiratory distress. In a completely counterbalanced factorial-within-subjects design, 27 intubated neonates were randomly assigned to two orders of presentation of treatment conditions. ⋯ Results indicated that clinically stable newborns tolerated instillations of 0.25-0.5 ml. The suctioning protocol used in this study minimized changes in infants' heart rates and blood pressures.

Biography Historical Article[Franz Kuhn (1866-1929) on the 125th anniversary of his birthday].
At the beginning of the 20th century, the German surgeon Franz Kuhn (1866-1929) was the leading protagonist of various endotracheal intubation technics. In the period between 1900 and 1912, he wrote several papers on this topic including a remarkable monograph on intubation, which was not widely appreciated for decades. In this, he discussed--among others--the advantages and possible risks of the endotracheal intubation, for patients during surgical procedures as well as in situations of cardiopulmonary resuscitation. ⋯ He was the first to incorporate a carbon-dioxide absorption system within the anaesthesia apparatus. Later, he developed technical devices for the perioperative intravenous administration of fluids or the injection of local anaesthetic drugs under high pressure. In honour of Kuhn's 125th birthday, the various contributions to anaesthesia and emergency medicine are outlined.

Intra-ocular pressure was measured before and throughout airway establishment with either the laryngeal mask airway or tracheal tube. Similar measurements were made on removal of either airway and the amount of coughing noted in the first minute after removal. ⋯ There was a significantly greater rise in heart rate using the tracheal tube (p less than 0.01) probably related to an increased cardiovascular response. The laryngeal mask airway is recommended as an alternative to tracheal intubation in routine and emergency intra-ocular surgery.
